. Specification of Application filed July as,

To all whom it may concern:

Be it known that 1, JOHN P. HARRISON, a citizen of'the United States, residing at Detroit, WVayne county, Michigan, have invented certain new and useful Improve ments in Adding and Listing Machines, of t which the following is a specification.

The present invention relates more par ticularly to the characterizing of the first item or amount added after a clearing operation for the purpose of denoting that the ac cumulator of the machine stood at zero when the adding began. For prior eXem-' plifications of means by which such result may be accomplished reference may be had to British Patents Nos. 18,516 of 1907 and 611-1 of 1908. Characteristics of the present manner of accomplishing the result are the employment of devices such as found in split and normal adding and listing niachines, to control the printing of the called clear sign; and the use of the accuthe set of adding wheels, to exercise control over the special printing devices. Thus, a. detent or latch which normally restrains a hammer for the special type is cooperatively related to similar detents or latches normally restraining the hai'mners which operate the amount printing types, though this cooperative,relationship is normally suspended andcan only be established when all of the adding wheels stand at zero and the operating handle of the machine has been drawn forward, or, in the case of a power driven machine, the driving shaft given its initial turning. Then with reference to the second mentioned characteristic the adding wheels are constructed or equipped so as to permit e'tt'ective movement of a cooperating clcmcnt (especially provided) when said wheels all stand at zero, said specially provided element by such movement ctlccting the establishment of coiiperativc special detcnt or latch and the other detents or'latchcs. Such manner oi desired result has the advantage of putting the special printing devices under the direct control oi the adding wheels themselves and the main operating element or prime. mover of the machine, thereby avoiding complication with the controlling devices through whose manipulation the clearing operation is brought about. I

In connection with such operations of the ITED OFFICE- ADDING AND. LISTING MAo mn relationship between the arriving at the out invention (the customary inclosmg cas Letters Patent. Patented Apr. 11, 1911 1909. Serial No. 510,090;

machine as those which strike totals and Subtotals, or print amounts without adding them, though the adding wheels"would be at zero positions in the middle of the ope'i tien, of course the clear sign shouldnotbe printed. In any such case, under the an i rangement provided by the present amen- 4 -tion, there would bethe same etfect as when theclcar sign should be printed in so far as concerns the establishment of coopcrlatiy I relationship between the special detent t l latch and the other detents or latclies.f But. t the clear sign will not be printed, for the], l l l sign type will be at the printing line, when the printing of the amount is none but wi only be operated when the ,addingwlieels stand at Zero. In other operations, such as totaling, subtotaling and eliminating,theI special type carrier will have been shifted v to bring one or another of the other special b types to the printing line. Consequently the, release of the special hammer in the latter case results in the printing ,of the a'ppropriate character. In a blank operation, with the adding wheels at Zero, though the col operative relationship above referred towill be established, yetthere will be no release of the special hammer since no one oi the, regular detents or latches is opcratcd and vturtlnirmore 'thc pawh which in some i11 stances would operate the special dctent or latch, will be disabled by encounter with the. l

term part of this specification Figure 1 100 represents in left side elevation an adding.

ot the well-known liarand listing machine applied thereto the presroughs type having t ing is omitted, as also the near side itrame piece, and the supporting base and 'papc carriage attaclnnent are shown. in scctioi'ilic Fig. 2. shows an examplcoi' printing done i by the machine; Fig. 3 is a right side clcva-' tion on the order of the left side elevation in Fig. 1, though not including quite so much of the machine; Fig. 4 is a view similar to Fig. 3 in representing parts in right Side elevation to some extent, other parts appearing in section and the view differing further from Fig. 3 in that a different relative positioning of parts is illustrated, to wit that which obtains when the handle of the machine has been drawn forward in an adding operation first ensuing after a clearing operation; and Fig. 5 is a sectional'plan view of certain portions of the machine taken substantially on the line 55 of Fig. 3.

The general construction is the same as that of the familiar Burroughs machine shown in the above mentioned prior patents and in numerous other patents not necessary to enumerate. It comprises the usual amount keys 291 controlling the extent of movement of racks (310 carried by levers 611 loose on a rock shaft (300 to which is secured a restoring frame or bail (313, such shaft being oscillated through connection with a handle shaft 300, Fig. 3. The adding wheels or pinions 916 are carried as usual in a rocking frame 910 worked by apitman tilt variously controlled by total key 29 subtotal key 293$ and elimination key 293E and familiar connections. The levers ($11 carry at their rear ends the usual series of type plates (31S adapted to be driven against the platen 17 by hammers 715. The latter are operated as usual by spring-actuated driving levers T16 normally restrained by latches 717 and the usual pawls 71S individually tripping said latches, said pawls being disabled by contact of their tails against inclined shoulders of the levers (ill but the latches being cooperatively related through the medium of overlapping tails (.7, Fig. 5, to provide for cipher printing.

in carrying out the present invention an additional printing hammer 715 is provided (Fig. 3), also an additional lnunmer driver 7th" and an additional restraining latch 7t? and an additional latch tripping pawl T18. special type carrier is provided in the form of a plate or arm (21 l loosely mounted on the shat't ($00 just to the right ol. the group of levers 611 and at its rear end this arm carries type plates MS, two in the present. instance, each having two type fa es and that designated 1, in the present instance the uppermost type, bearing the clear sign (e). The next lower type, designated 2, bears the elimination sign (ii). The third type, designated 3-, bears the sign indicating a grand total The fourth and last. special type. designated 1, bears the sign indicating a subtotal lhis special type carrier has an inclined shoulder a like the inclined shoulders of the levers ill t, for di+ abling the special pawl HS" whenever the hin i:- -'.-p-'-atcd with the special type t l l l l l l l l l l carrier moved no higher than the position where the number sign type 1 is at the printing line. Ther'e projects from one side o l the special type carrying arm (311 a stud c, Fig. 3, for coacting with an index arm A which is formed along the under edge of its broadened lower extremity with a series of ste s or shoulders 1, 2, 3 and 4; allotted to the several special types respectively. A spiral spriing 611 tends to draw the special type carrier upward and carry its stud 0 against; the said indexing arm A, but normally the spring is restrained by reason oi the fact that an arm (30.0 secured to the shaft tltlt) bears with a lateral lip against a forward projection (311 of the special type carrier as shown in Fig. 3, depressing the rear portion of the latter. The beforen1entioned stud nor mally stands opposite the shoulder 1 slightly sep .rated therefrom as shown in Fig. 3, and in any operation of the niachine without depression of total, subtotal or elimination key the stud moves up against said shoulder bringing the clear sign type 1 squarely to the 'n'inting line, but unless the adding wheels already stand at zero and one or more amount keys 291 have been dcpressed this clear sign type will not be driven against the platen because the inclined shoulder Z) of the special type carrier still lies in the path of the special pawl 71S and other means presently to be described, by which the special latch 71.7 may be tripped, will not come into play. Referring next to such other means For tripping the special. latch 71?, there is pivoted to the same a bar or pitman n which extends forward, having a bifurcated portion guided in the groove of a supporting rod B, and this bar or pitman has pivoted to it. at the point 6 (Figs. 3 and 5) a catch piece 0 connected by a spiral spring 6 to an ovcrl'iead portion of the framework. A laterally projecting lip c of said catch piece extends to the left under a bar or pitman 0" which is pivoted. at its rear end to the units latch T17 and has a shoulder r, Fig. 3 in trout of which the lip v is adapted to engage so that a tripping move-- ment of said units latch will be communicated to the latch 717. llowever, said catch piece is normally depressed so that said lip is out ol line with said shoulder. Said catch piece is constrained to occupy this position against the stress of the spring 0 by a linger c which normally presses down upon the. upper edge ol the catch piece, as illustrated in Fig. 3. Said linger 6 is integral with a yoke l) pivotally mounted upon a stud on the framework. An upstanding arm c" recared to said yoke has a stud c which is en gaged by the bit'mrazr l upper end of the upwardly extending arm I) ot a bell crank lever pivoted at l) to the framework and whose other arm l)'-' extends Forward to a point. adjacent the adding wheels 916.

llt

spiral spring I) applied to thearm D said bell crank lever'tends to raise said arm and throw the arm 1) rearward, rocking the yoke E and permitting the catch piecee to rise andv couple the jaeent or units latch Said bell crank lever is normally restrained, however by reason of the engagement of astud 30 with a curved edge d of the arm D*, said stud being; carried by the full stroke sector 2511 which is secured to the operating shaft 300. This curred edge Zis normally concentric wit 1 said shat't as shown in Fig. 3, so that during the greater portion of the turning of suit shaft, due to the torward pull of the operating handle, the stud travels along such edge without permitting the bell crank lever to more. In rear of the curvededge '11 there is a lower shorter curved edge it and between the two curved edges there is a short and somewhat abrupt cam edge (7.

In the movement of the tall stroke sector 3'11 llGyUTKl that. accompanied by any down- .wttrd travel of the racks ($10 the stud 30 passes the cam edge rl so as to permitsutlicient. movement oi the hell crank lever to rock the yoke E and allow the coupling to he elt'ected between the s1; ccial latch and the units latch, as illustrated in Fig. 4, such movement of the bell crank lever bringing" the edge into concentricity 300. However. such movei'nent of the bell crank lever :annot take place unless all of the adding wheels 91G stand at zero. There is secured to each one of these wheels a disk 1*, Fig-5, and at a corresponding point in each '01" these disks there aperipheral notch f'.- The forward end of the bell crank arm l) is biturcated to embrace a cross rod G of a rocking; frame comprising side pieces 1 and 5/ of angular outline (see Fig. 3) and a second cross rod G extending between the same,-said side pieces being pivoted at their forward ends to the side pieces ot the accinmilator frame 910 as indicated at cross rods (l and Mounted upon the and G are a series of plates 9" having; squared projecting ends or fingers g" adapted to engage the notches j rcspectirely. The cross rod G is securely clamped to the side pieces 1 g and it will be seen that when the hell crank arm l3 mores this rocking- -t'rame must move with it. The peripheries of the disks F lie close to the ends of the and unless all of the notches f have been brought opposite the projections y ot said plate; the rocking frame will be obstructed by one or more of the disks and the bell crank lever cannot be rocked by its spring D notwithstanding the stud 2-30 has passed the cam edge (7 Said notches are so lo cated as to come exactly ojnmsitethe projections f/ respecti\'el when the wheels all stand at zero. At the conclusion of clearing operation of course the wheels are lett latch 71'? to the'adwith the shaft of l at zero and the special latch and one or more amount keys have been de l j l reason of the cooperative act ing handle, when it carries the stud 30past the cam edged will result in rockingof the bell c ank lever and a coupling together of the units la'tcl t pressed without depression of the'eli'n'timition key then the tripp ng ot thespec al latch by reasonof the tr1pping of the units latch will cause the special hammer ili t top then the next pull of the operaty drive the clear sign type 1 against (the platen" and characterize the printed amount a] the first added after the clearing operation. It will of course. be understood that the timing of the parts is such that. the stud 30in the return ol the ope ating handle rides over the cam edged withdrawing the projection (Z front the notcheslj' before any of the racks (310 are started upward,

It. will be seen that in at taling or subtotaling; operation the adding wheels-wiil when the stud 30 passes the and consequently the .bell to together the special latch and the units latch and the same thing would be true it" alter a clearing; opcration the elimination key was depressed stand at zero cam edged .in connection with the'next subsequent operation. However, in any such case the clear sign type. will not be and the release of the. special hannncrlby iondue'to such coupling; of latches or in some other way would be desirable, as this same haiinncr is to etl'ect'the printing of total, elimination sigzns. In case of characterizing a total or subtotal it might be sutiici'ent to rely upon this cooperativeaction, but of course an eliminated amount or munber may occur .Then the special pawl T18 would'be relied by the regular bail u, acted. upouby upon to trip the special latcln it behr; aadcrstood otcourse that said pawl carried which swings back. and forth in every operation of the machine.

The 'im'loxing arm is secured to a rockshaft. 206 which extends below the keyboard in the machine to the left-hand side thereot, where there is secured to it an arnrA' (Fig. l) carrying studs (4 u projecting from opposite sides, the former acted upon by the subtotal key bell crank jleverFZ'ZTS and the stud. a cam edge 72 on the stem of the, elimination key 293E. The total kc bell crank lever 22? is as usual connected 22b with the amount key releasing by a link bail. ln tbepresent instance said link. has a stud (1. adapted to act upon said arm A, The arm is moved ditt'erent. distances. ac-

Depression of the total k y 2913 swings the arm A and indexing arm a greater distance, bringing the shoulder above the stud c and causing the special t vpe carrier to be swung upwardly so as to locate the total sign type. 53 at the printing line. Dcprcssion oi? the subtotal he swings the arms A. A still farther, locating the shoulder t" above the stud c and in t ensuing operation of the machine permitting the special type carrier to swing upwardly, bringing the subtotal sign type -t to the printing line.
